Fig. 2. Structure of amphiphilic triblock copolymers Pluronic F-127 and Pluronic P-123 (Sigma-Aldrich, USA), where a represents the number of hydrophilic monomers and b represents the number of hydrophobic monomers. For Pluronic F-127, the a-b-a formula is 98–67–98. For Pluronic P-123, the a-b-a formula is 20–70–20
